Obtain RAW SAR data

Nine RAW SAR images (L1.0) are acquired from https://asf.alaska.edu/. The data can be easily obtained by searching the scene name (ALPSRP020160970, ALPSRP054200670, ALPSRP103336310, ALPSRP110940620, ALPSRP115120970, ALPSRP268560540, ALPSRP269950430, ALPSRP273680670, ALPSRP278552780) in https://search.asf.alaska.edu/. The worldmaps of these images are illustrated as follows:

Making Dataset

The download nine sar raw images are imaged by Range Doppler Algorithm (RDA). Since the orignal image is very large, sub-region with size of $8192×8192$ is selected for each image. The selected regions are shown as follows:


Vancouver, ALPSRP020160970	Xian, ALPSRP054200670	Hawarden, ALPSRP103336310
Hefei, ALPSRP110940620	Langley, ALPSRP115120970	Florida, ALPSRP268560540
Kaliganj, ALPSRP269950430	SimiValley, ALPSRP273680670	Toledo, ALPSRP278552780
